Bed bugs
Taming the itch
Bed bugs are notoriously difficult to detect and even more difficult to eradicate. They are nocturnal insects that feed on human blood. They live in bed sheets, bookshelves, couches, bed frames; just about anywhere they can get access to blood. Most often, they bite human hosts while they are sleeping, and so the host does not feel the sensation of being bitten. Because of this, the bed bug can feed repeatedly and for long periods of time. This is why a person rarely has one bed bug bite, but dozens.
